I love the softness, warmth, design, color and fit of this. I used to knit a lot, and can confirm that this is high-quality work. My favorite sweater. I'm 5'5 and 125-130 lbs and the medium was a perfect relaxed fit which is what I prefer..
Alpaca is wonderful to touch with softness and thickness, giving such warmth in the winter.
When I was in Peru on a train to Cusco, similar pieces were sold much more expensive.
